Survey of Question Answering Approaches in Health Care

Vocabulary gap between health seekers and health providers which delayed the cross-system operability and the interuser reusability. Approaches for local-global learning are discussed in this paper. Local mining extracts medical concepts from the QA pair itself and maps them to authenticated terminologies. Global learning, works towards enhancing the local mining via collaboratively discovering missing key terminologies and keeping off the irrelevant terminologies by analyzing the social neighbors. The rise of digital technologies has transformed the doctor-patient relationships. In this new era of web, when people struggle with their health concerns, most of them usually explore the Internet to research the problem before and after they see their doctors. A dictionary of vocabulary is constructed as a by-product, which is used as the terminology space for global learning.
